Change kernels often? Natively booting via UEFI?
A while ago I gave up on grub and starting booting natively using UEFI and my BIOS. This has worked well, but I often change kernels and I needed a way to easily boot a different kernel by default. I used to do this by reviewing the entries from efibootmgr and manually updating them, but this was cumbersome and error prone. Well, not any more:
```
$ sudo Scripts/efibootset
Current EFI boot order
1) Boot0009 - Void Linux with kernel 6.15.9_1
2) Boot0008 - Void Linux with kernel 6.15.4_1 [Currently booted]
3) Boot0007 - Void Linux with kernel 6.12.41_1
4) Boot0002 - Void Linux with kernel 6.12.40_1
5) Boot0006 - Void Linux with kernel 6.15.7_1
6) Boot0000 - debian
7) Boot0001 - Linux-Firmware-Updater

sshPilot 2.0 released with tunelling support and more
Main window
sshPilot is a desktop application for managing SSH connections. It loads/saves standard .ssh/config entries and make it easy to manage multiple servers.
It fully supports dynamic, remote and local port forwarding, key-pair generation, file transfer to remote machines and more.
Fetures:
- Load/save standard .ssh/config entries (it loads you current configuration)
- Tabbed interface
- Full support for Local, Remote and Dynamic port forwarding
- Intuitive, minimal UI with keyboard navigation and shortcuts: Press ctrl+L to quickly switch between hosts, close tabs with ctrl+w and move between tabs with alt+right/left arrow
- SCP support for quickly uploading a file to remote server
- Generate keypairs and add them to remote servers
- Toggle to show/hide ip addresses/hostnames in main UI
- Light/Dark themes
- Customizable terminal font and color schemes
- Free software (GPL v3 license)
The app is currently distributed as a debian package and can be installed on recent versions of Debian (testing/unstable) and ubuntu. Debian bookworm is not supported due to older libadwaita version.
Latest release can be downloaded from here: https://github.com/mfat/sshpilot/releases/
You can also run the app from source. Install the modules listed in requirements.txt and a fairly recent version of GNOME and it should run.
A Flatpak and an RPM version are also planned for future.
I'm also looking for a volunteer to design a good icon for the app.
I'd highly appreciate your thoughts/feedback on this.

What's the best offline capable information resource on linux?
I was thinking about how wikipedia lets you download the whole site as a html file. Is there anything like that for information on linux?
This is perhaps becoming more meaningful in a world where corporate and governmental powers are gaining further and further control over the internet, and climate change is also threatening data centres, particularly in terms of the water requirements.

Linux is one of the best gaming platforms right now
It’s not perfect, sure (anti-cheat is still a pain in the ass) - but the problem is, people keep comparing it to Windows, which obviously has a way bigger market share and way more years of direct support from devs and companies.
Comparisons can be useful for pushing Linux gaming forward, but they can also make us forget how far it’s already come.
And honestly, in 2025, Linux is a very mature gaming platform:
Drivers are constantly improving, and if you’re on AMD or Intel, you don’t even need to install them manually - just plug in your controller and play.
There are over 21,000 games available on the biggest gaming store - Steam (straight from your distro’s store) with cloud saves, automatic updates, and free online play.
Epic, GOG, or Amazon games? Install Heroic (also in your store) and you’re set.
Retro gaming? You’ve got emulators for pretty much anything - PS1, PS2, PS3, GameCube, SNES, Xbox, you name it - all right there in your distro's store.
Steam Deck, SteamOS.
DXVK, VKD3D, Vulkan and Proton are improving all the time.
And also tools like MangoHud for hardware info.
There are even distros made just for gaming, like Bazzite.
Even some big tech influencers are making videos about Linux gaming now. So Basically… gaming on Linux in 2025 is awesome. And I just love how good it has become.
EDIT: Some people here are misunderstanding the point of this post. It’s meant to be a celebration of what Linux is right now as a gaming platform - and it’s actually a very good one. At no point am I saying it’s better than Windows or making any direct comparisons. Like I said in the post:
"Comparisons can be useful for pushing Linux gaming forward, but they can also make us forget how far it’s already come."

Btrfs at Scale: How Meta Depends on Btrfs for Our Entire Infrastructure BY The Linux Foundation (May 25, 2023)
Video (41 min): Btrfs at Scale: How Meta Depends on Btrfs for Our Entire Infrastructure - Josef Bacik, Meta
Explained by Phoronix :
Josef Bacik, a prominent Btrfs engineer at Meta, wrote about the magnitude of impact for Meta's Btrfs usage:
>"The Meta infrastructure is built completely on btrfs and its features. We have saved billions of dollars in infrastructure costs with the features and robustness of btrfs."
With the scale to which Meta operates and their massive infrastructure, Btrfs is attributed as having saved "billions of dollars" thanks to its advanced feature set and robustness. An interesting anecdote for those that continue to question Btrfs or its suitability for use in production environments.
More commentary can be found via this LKML thread amid the ongoing discussion over Bcachefs in the mainline Linux kernel.

Exactly. Which is why the Meta infrastructure is built completely on btrfs and
its features. We have saved billions of dollars in infrastructure costs with the
features and robustness of btrfs.
Btrfs doesn't need me or anybody else wandering around screaming about how
everybody else sucks to gain users. The proof is in the pudding. If you read
anything that I've wrote in my commentary about other file systems you will find
nothing but praise and respect, because this is hard and we all make our
tradeoffs.
That courtesy has been extended to you in the past, and still extends to your
file system. Because I don't need to tear you down or your work down to make
myself feel good. And because I truly beleive you've done some great things with
bcachefs, things I wish we had had the foresight to do with btrfs.

Video (41 min): Btrfs at Scale: How Meta Depends on Btrfs for Our Entire Infrastructure - Josef Bacik, Meta
Explained by Phoronix :
Josef Bacik, a prominent Btrfs engineer at Meta, wrote about the magnitude of impact for Meta's Btrfs usage:

With the scale to which Meta operates and their massive infrastructure, Btrfs is attributed as having saved "billions of dollars" thanks to its advanced feature set and robustness. An interesting anecdote for those that continue to question Btrfs or its suitability for use in production environments.
More commentary can be found via this LKML thread amid the ongoing discussion over Bcachefs in the mainline Linux kernel.
